It doesn't have to be the roofIn the early years, photovoltaic units were predominantly installed on the roof of the house, but the design options and the possibilities for integrating them into the building have since increased enormously. Nevertheless, the type of installation is still dependent on the type of building and the local circumstances. On-the-roof installation
In this case, the photovoltaic panels are mounted on a special substructure around 5 – 15 cm above the roof. Because of the simple construction, costs are lower than with the more complicated in-the-roof installation.  In-the-roof installation
Aesthetically, integration into the existing roof area is the most elegant solution, but it has the disadvantage of poorer ventilation.  Flat-roof installation
Here, the modules are mounted at an angle on a special frame to capture as much of the solar radiation as possible. Large unobstructed roof areas are suitable for flat-roof installation.  Facade installation
A distinction is made between cold and warm facades. With cold facades, the modules are installed subsequently in front of the facade and serve both for generating energy and for offering protection against the elements. The term warm facade is used to describe an outer wall built entirely of photovoltaic modules that can assume all the desired functions, ranging from the "skin" of the building to heat insulation.  Open-land installation
For this type of installation, large unobstructed areas of ground are needed. This type of photovoltaic system is particularly interesting for local communities and farmers. |
